T0 aZZ whom it may concern:

Be it known that we, J EAN FRANCOIS GEEs- BERGEN and ALFRED GERUZET,both subjects of the King of Belgium, residing at Brussels, Belgium,have invented certain new and use ful Improvements in PhotographersElectric Retouching Devices, of which the following is a specification.

Our invention relates to improvements in an apparatus operatedelectrically for v retouching photographic negatives; and it has for itsobject to provide means whereby the retouching of photographic negativesor pictures is facilitated and the work performed in much less time thanthis could be done by the ordinary process of retouching.

In the accompanying drawings, Figure l is couples or other suitablegenerator, the two' pole wires of which (suitably insulated) are formedinto a flexible cable, K, that passes through the top of the casing tothe electromagnets, as hereinafter described. On top of easing A is alsolocated a commutatorto-regulate the power of the electric current.

B is a standard secured to top of case A, in the upper end of which ispivoted a supporting-rod, O, in which is formed alongitudinal slot, 0.The pivot-pins c of the rod 0 are formed on or secured to a slidingblock, 0 whereby the rod 0 is adapted for longitudinal adjustment on thestandard B, so that the devices supported from said rod may becounterbalanced, for which purpose the rod is provided with acounter-weight, I), having a screw-threaded stem, I), screwed in the endof the rod 0. To the opposite end of rod 0 is secured a rod,' O, towhich is pivoted a helical spring, E, by means of a forked bearing,

6. The opposite end of the flexible helical spring E carries a secondforked bearing, H, pivoted to the spring'at h,and at h to a frame orsupport, D, that carries the electro-magnet D and its armature G, saidframe being provided with suitable binding-posts, d, Fig. 2, for theelectrical conductors of cable K, connecting the electro-magnets withthe generator in the usual way, as shown. The armature G is secured to aflexible spring, upon the free end of which bears an adjusting-screw, I,for regulating the extent of the vibrations or oscillations of the frameD.

The pencil-holder M is connected by means of a flexible helical spring,L, to a head, J, secured to the frame D by means of a screw or screws.The holder consists of an outer tube terminating in a swell or collar,1), in which is fitted abindingscrew, V, whereby the pen oil N is heldin position. WVithin the holder is fitted a collar, 0, adjustablelongitudinally by means of a set-screw, 0, that passes through a slot inthe tube M. This collar 0 serves as an abutment for one end of a helicalspring, Q, the other end of which is secured to the outer hooked end ofa rod, R, that slides freely through the collar 0, and is secured to atubular carrier, P, for the pencil N. By means of the rod R- and springQ the course of the pencil is regulated, and the tension of the spring Qis regulated by the adjustment of the collar 0 within the holder M, aswill be readily understood.

It is evident that when an electric current passes through theelectro-magnetsa rapid oscillatory or vibratory movement is imparted tothe frame D, and through it to the head J, holder M, and pencil N,producing a rapid stippling upon the surface acted upon.

By means of the flexible connections L h h E e and the oscillatingsupport 0 a wide range of movement is imparted to the tool, while thereis sufficient rigidity of the parts toproperly transmit the vibrationsof the frame of the electro-magnet to the pencil.

By providing means for counterbalancing the weight of the pencil-holderand electromagnet on their oscillating support the oper- Lil ator isrelieved of any weight on his hand,and has therefore only to guide thepencil over the work, and by this means he is better enabled to regulatethe depth of shade required with considerably less fatigue.

In retouching photographic negatives or photographic pictures, it issometimes desirable to do this by lines instead of stipplin or by bothlines and stippling.

To produce lines weemploy the holder shown in Fig. 3, in which the outertube, M, contains an inner tube or pencil-carrier, P, of nearly the samelength as tube M, but of sufficiently less diameter to adapt the tube tooscillate in a direction at right angles to the longitudinal axis of theholder. To this end the carrier 1? is pivoted at or near itslongitudinal center to a collar, S, that carries the pivot studs orscrews 3.

To the upper end of the tubular carrier 1 is secured a bent arm orplate, T, that passes through the holder M, and against which impinges atongue or extension, l, adapted to be secured to the outer or free endof the armature G. A spring,'\, secured within the tubular holder M,serves to return the carrier P to its normal position after eachmovement from one side of the holder M to the other on its pivots s.

It is evident that the vibration of the armature G will be communicatedto the carrier 1? and pencil N through the actuating arm or tongue G andbent arm T, and said pencil, instead of being reciprocatedlongitudinally, will be reciproeated horizontally and produce lines.

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is-

1. A photographer s electric retouching device, composed of a pivotedsupport, an electro magnet suspended therefrom, a pencilholder flexiblyconnected with said electromagnet, and suitable electrical conductors,substantially as described, for the purposes specified.
